Frequently Asked Questions

1. What is a dash cam?

A dash cam is a small in-car camera that continuously records the road while you drive. Depending on the model, it may also record the rear of your vehicle or the cabin and can include features such as GPS, Wi-Fi, Parking Mode, and voice control.

2. Do I really need a dash cam?

While a dash cam isn't legally required in most countries, it can provide valuable evidence after accidents, insurance disputes, hit-and-run incidents, or vandalism. It's one of the most useful safety accessories you can add to your vehicle.

3. How does a dash cam work?

A dash cam automatically starts recording when it receives power. Video is stored on a microSD card, and Loop Recording continuously overwrites the oldest unlocked footage to ensure recording never stops.

4. Is a 4K dash cam worth it?

For many drivers, yes. A 4K dash cam captures more image detail than 1080P, making it easier to read license plates and road signs. However, overall image quality also depends on the image sensor, HDR, and image processing.

5. Is 2K enough for everyday driving?

Yes. A quality 2K dash cam offers an excellent balance between video clarity, storage efficiency, and price, making it a great choice for many daily commuters.

6. What resolution should I choose?

  • 1080P – Budget-friendly and suitable for basic recording

  • 2K – Great balance of quality and storage

  • 4K – Best for maximum detail and highway driving

Choose the resolution that best matches your driving habits and storage requirements.

7. What is Sony STARVIS 2?

Sony STARVIS 2 is an advanced image sensor technology that improves low-light sensitivity and dynamic range. It helps produce clearer recordings at night and in challenging lighting conditions.

8. What is HDR?

HDR (High Dynamic Range) balances bright and dark areas in a scene. It helps reduce headlight glare and preserve detail in shadows, making it especially useful for night driving.

9. What is Parking Mode?

Parking Mode allows a dash cam to monitor your vehicle after the engine is turned off. Depending on the model, it may record when motion or impacts are detected or use time-lapse recording to extend surveillance time.

10. Do I need a hardwire kit?

A hardwire kit is recommended if you want Parking Mode. It supplies continuous power to the dash cam and typically includes low-voltage protection to help prevent excessive battery drain.

11. Will Parking Mode drain my car battery?

Most hardwire kits include low-voltage cutoff protection, which automatically disconnects power when the battery reaches a predefined level to help protect your vehicle's battery.

12. Do I need Wi-Fi on a dash cam?

Wi-Fi isn't essential, but it makes downloading videos, viewing live footage, adjusting settings, and updating firmware much easier through a mobile app.

13. What does GPS do on a dash cam?

GPS records your vehicle's location, speed, and route alongside the video footage. It does not provide navigation but adds valuable context to recorded events.

14. How much storage do I need?

A 128GB High Endurance microSD card is suitable for most drivers. If you record in 4K or use multiple cameras, a 256GB card is generally recommended, provided your dash cam supports it.

15. What is Loop Recording?

Loop Recording automatically overwrites the oldest unlocked video files when the memory card becomes full, allowing your dash cam to continue recording without manual intervention.

16. Where should I mount my dash cam?

The best location is usually behind or just below the rearview mirror. This provides a clear view of the road while minimizing distractions and keeping the camera out of the driver's line of sight.

17. Should I choose a front-only or front-and-rear dash cam?

For most drivers, a front-and-rear system is recommended because it records incidents from both directions and provides better evidence in rear-end collisions or parking incidents.

18. How long does it take to install a dash cam?

A front-only dash cam typically takes 20–30 minutes to install. A dual-camera system with concealed wiring may take one to two hours, depending on your vehicle and installation method.

19. Which features are most important?

The most useful features for most drivers include:

  • High-quality image sensor

  • 4K or 2K recording

  • HDR

  • Front & rear cameras

  • Parking Mode

  • GPS

  • Wi-Fi

  • Loop Recording

  • High Endurance microSD card support

Choose the features that match your driving environment and daily needs.

20. Which GKU dash cam is right for me?

  • GKU D600 Pro Max – Ideal for everyday driving, featuring 4K front recording, a Sony STARVIS 2 front sensor, HDR, GPS, Wi-Fi, and Parking Mode support.

  • GKU E200 – Designed for drivers who prioritize maximum recording detail with True Dual 4K recording.

  • GKU D1000 – Recommended for Uber, Lyft, taxi, and fleet drivers who require front, rear, and interior recording.

The best model depends on your driving habits, budget, and the features that matter most to you.

  • Will your vehicle be parked outdoors for long periods?
  • Do you want convenient features like Wi-Fi and GPS?
  • What's your budget?

Answering these questions will help you choose a dash cam that fits your real-world needs rather than simply chasing the highest specifications.

A dash cam is an investment in safety, peace of mind, and reliable evidence when unexpected situations occur. Choosing the right one today can provide years of dependable protection on every journey.
